United States Patent U.S. Cl. 52-18 1 Claim ABSTRACT F THE DISCLOSURE In a single-story dwelling house of trifurcate conguration Of general Y-shape in horizontal section the three branches of the trifurcate configuration are substantially symmetric each in respect of one of three vertical planes intersecting at the center of the house. Three walls, each in one of said planes, radiate from the center of the house to divide the interior thereof into apartments. The roof of the house is formed above each of said three walls with two slopes which extend longitudinally of the respective wall and in cross section leave between them an upwardly open angle. In the slopes of the roof there are skylights for the apartments into which the interior of the house is divided by said walls.

The present invention has for its object to provide a single-story dwelling house of trifurcate configuration of general Y-shape in horizontal section. The invention is primarily characterized in that the three branches of the trifurcate dwelling house have three vertical planes of symmetry which each contain one wall, the resulting three walls thus radiating from the center of the house to divide the interior thereof into apartments, and above each of said walls the roof of the house has two slopes which extend longitudinally of the respective wall and in cross section leave between them an upwardly open angle, skylights for the apartments being arranged in said slopes of the roof to admit light from above into the apartments on either side of the wall separating them. To obtain a complete symmetry of the house in respect of each of said three planes of symmetry, said planes have a common line of intersection at the center of the house and are arranged at mutual angular distances of 120 about said line of intersection. It is suitable to have the house divided into three apartments by the apartment-dividing walls extending in said vertical planes of symmetry and to have the ceiling in each of the three apartments formed with a portion that makes a downwardly open angle with the roof slope having skylights for the apartment and reflects the light falling through the skylight towards the apartment-dividing wall. At the top said wall may be of channel-shape to lead away rain water from the two roof slopes making an upwardly open angle with one another and having the skylights for the apartments therein.

By applying, in practising the present invention, this principle of trifurcate configuration of Y-shape in planning housing areas of single-story dwelling houses, one gains the advantage that apartments which would otherwise be badly positioned in respect of the cardinal points will come to occupy the perhaps best position in point of incident light and sunrays. In any case, the invention provides a considerably increased freedom of housing devel- "ice lment without neglecting either the requirement of an advanced standardization and rationalization of housing production, or the requirement that all apartments should have ample sunlight. The complete symmetry of the house in respect of each of said three vertical planes is particularly advantageous for realizing an advanced standardization and rationalization of housing production. The secondary characteristic features also contribute to simplify housing production and to make it less expensive or to increase the homeliness of the apartments and the eect of the skylights thereof,

The above features of the invention will become more fully apparent from the following specification in which reference is made to the accompanying drawing illustrating'a preferred form of the invention.

In the drawing:

FIGURE 1 shows an example of two built-together single-story dwelling houses of trifurcate configuration of Y-shape, the left house being shown in a top plan view and the right house in a horizontal section taken immediately beneath the ceiling;

FIGURE 2 on a larger scale shows a vertical section on line II-II in FIGURE 1.

In the drawing, the walls giving the house its trifurcate configuration of Y-shape are designated 1 and the apartment-dividing walls 2. The latter walls are arranged in three vertical planes intersecting at the center of the house, and the three branches of the house are symmetric each in respect of one of said three planes which are spaced angularly from each other about said line of intersection or the center of the house by an angle of The walls 2 divide the house into three apartments, but it is of course possible to combine for instance two of these apartments into one having a communication through an opening in the respective wall 2. The interior decoration of the apartments lies outside the invention and can be varied at will. The invention deals, on the other hand, with the configuration of the roof 3 of the house, inasmuch as said roof 3 above each of three apartmentdividing walls 2 has two slopes 4 making an upwardly open angle with one another, while the skylights 5 for the apartments are provided on either side of the wall 2, the ceiling 6 of each apartment having a portion 7 that makes a downwardly open angle with the roof slope 4 having the skylights 5 and reliects the light falling thereon from the sky towards the adjacent wall 2. At the upper end the wall 2 is formed with a valley 8 for leading away rain water from the two slopes 4.

What we claim and desire to secure by Letters Patent is:

1. A single-story dwelling house comprising walls confining a trifurcate configuration of general Y-shape in horizontal section of the house, the three branches of said trifurcate configuration being substantially symmetric each in respect of one of three intersecting vertical planes, walls in said vertical planes to divide the interior of the house into apartments, a roof covering the interior of the house, two slope portions of said roof being situated above each of said walls in said vertical planes and leaving between them an upwardly open angle, and skylights in said slope portions for the apartments on opposite sides of the respective one of said walls in said vertical planes, the underside of said roof forming in each of said apartments a ceiling having adjacent to the roof slope having the skylights for the respective apartment an inclined por- References Cited UNITED STATES PATENTS Olson 52-18 X Buckwalter 52-18 Nobbs 52-18 X Horowitz et al. i 52-18 10 4 Y FOREIGN PATENTS 3/ 1964 Belgium. 4/1964 Sweden.
